Currently memory allocation for multiple hardware rings
done in host as these memory will be used by firmware/hardware.
But in case of tcl_cmd_ring and tcl_status_ring neither firmware
nor hardware uses host allocated memory and it uses memory allocated
by firmware itself. So avoid tcl_cmd_ring and tcl_status_ring setup
in host.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
